Process for production flashing

[Richard D.]

Having spent some number of hours figuring out production flashing and field updates, I think I now understand the current methodology. The biggest challenge was to sort out the many obsolete forum posts.  There are other variations (e.g. bootloader update OTA), but I think the overall process is right.  Corrections and clarifications are greatly appreciated.

Hi,

The overall process that you outlined is correct, and we should probably have included a similar illustration in our documentation. It's unfortunate that this process is not made more clear in the SDK documentation. I will report this internally. 

In the meantime, here are some relevant links:

• Bootloader memory layout (overview of typical memory layout with sd+bl+app)
• Bootloader settings page
• Generating DFU packages
• Generating BL settings page (settings page needed to validate app when uploaded through debug interface and not through DFU)
• Merge tool (Can be use to generate a single hex file containing sd+bl+app+bl settings)
